How to run google chrome headless in docker?
My problem is how to run google chrome in docker container for e2e testing.
I create a Dockerfile from official Jenkins image, but when try to run google chrome, it crashes and show the error:
Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted
Trace/breakpoint trap (core dumped)
The Jenkins docker image uses Debian jessie.
I can run google chrome with --headless flag and the X server is not needed.
This is my docker file:
- https://github.com/ripper2hl/jenkinswithchrome
Jenkins official image:
- https://github.com/jenkinsci/docker
The repo a person runs google chrome with GUI from docker:
- https://github.com/jessfraz/dockerfiles/blob/master/chrome/stable/Dockerfile
My first approach is to use xvbf, but the process is more simple when used --headless flag.

I can run chrome in Ubuntu server with the same commands for installation, but in docker it fails.
After other intents, I used --no-sandbox flag, but docker images shows the next error.
[0427/180929.595479:WARNING:audio_manager.cc(295)] Multiple instances of AudioManager detected
[0427/180929.595537:WARNING:audio_manager.cc(254)] Multiple instances of AudioManager detected

Actually I ran this command:
google-chrome-stable --headless --disable-gpu --no-sandbox http://www.google.com
Solution 1:
Just launch chrome with --no-sandbox that s resolves the problem
Solution 2:
Using this image alpeware/chrome-headless-trunk worked for me in ubuntu!
The command used in that container to launch headless chrome is this:
/usr/bin/google-chrome-unstable \
--disable-gpu --headless --no-sandbox \
--remote-debugging-address=0.0.0.0 \
--remote-debugging-port=9222 --user-data-dir=/data
here's a short video of the container in action
I launched the container in Ubuntu with this command:
docker run -it --rm -p=0.0.0.0:9222:9222 \
--name=chrome-headless \
-v /tmp/chromedata/:/data alpeware/chrome-headless-trunk
then used Chrome to connect to the debug port at localhost:9222
With some modifications you could probably get this running in Jenkins!
